The Manthorpe Dual Swift Brick has been developed in conjunction with major house builders and conservation experts to improve the biodiversity of the built environment, providing a safe, spacious and habitable area to allow swifts to nest within the construction of modern houses. The compact design of the Dual Swift Brick allows it to work with narrower cavity wall details down to 50mm, making it ideal for modern timber frame constructions.
